M is for Milky Way vs. Andromeda

We live in the Milky Way galaxy, which is a spiral galaxy.  Our neighboring galaxy, Andromeda, is also a spiral.  Andromeda is also the only galaxy moving toward us while all other galaxies are moving away.  It's been predicted that billions of years from now, the Milky Way and Andromeda will merge to form a new galaxy altogether.  To see some spectacular predictions of how that will occur, watch the video below.


  1. See this freaks me out. The idea that the Andromeda and Milky Way will collide and merge really shakes the foundations of what you think is "permanent". Imagine the nightsky in 3 Billion years. That giant galaxy just sitting out there.

  2. That's interesting. I think my kids will enjoy watching this video.
